Sleep Disordered Breathing

Objective Assessment of Tongue Function and Endurance in Sleep-Disordered Breathing (SDB)

Objective Assessment of Tongue Function and Endurance in Sleep-Disordered Breathing (SDB)

SDB, which include Obstructive sleep apnea (OSA) and snoring, are conditions characterized by partial to complete collapse of the soft tissues around the pharynx during inhalation while sleeping.

The Tongue’s Role in Airway Stability

Lingual factors supporting airway collapsibility: A dysfunctional tongue fails to maintain a stable palatal position. When the tongue is low and receded in relation to the mandible, it promotes mouth breathing, which narrows the pharynx.

Factors affecting muscle responsiveness: A dysfunctional tongue may either overwork or underperform, leading to fatigue and reduced endurance. During an obstructive sleep event, the tongue may not generate enough force to counteract or limit the obstruction.

The Value of Objective Measurement

Assessing tongue strength and endurance helps identify neuromuscular factors that may impact SDB endotypes during sleep.

TPMD in Clinical Evaluation

TPMD supports:

  • Objective assessment of tongue force and endurance
  • Identification of functional risk profiles

Monitoring of combined treatment strategies that include rehabilitation with a retraining device (TRP) or Myofunctional Therapy
